Respectively, Cambria was the Roman name for Wales, and the Ordovices. These eons are divided verfebrados four eras of unequal length—Precambrian,Paleozoic,Mesozoic, and Cenozoic. Each era is divided into periods,and periods into epochs. Only epochs of the Cenozoic are listed vertebraos this figure. Devonian verrtebrados named for rocks near Devonshire, also on British soil. In North America, coal-bearing rocks of this age match with the Lower and Upper Carboniferous; American geologists sometimes refer to these divisions of the Carboniferous as the Mississippian and Pennsylvanian periods, after rocks in the Mississippi Valley and the state of Pennsylvania.
The Permian, although named by a Scotsman, is based on rocks in the province of Perm in western Siberia. The Triassic takes its name from rocks in Germany; the Jurassic from the Jura. Mountains between France and Switzerland; and the Cretaceous from the Latin word for chalk cretawhich refers to the white chalk cliffs along the English Channel. It was once thought that geologic eras could be dividedinto four parts—Primary, Secondary, Tertiary, and Quaternary—oldest to luvro, respectively. This proved untenable for the eras, but two names, Tertiary and Quaternary, survivein U.
Internationally, however, these terms are replaced with Paleogene and Neogene. Throughout the geological timescale, periods divide into epochs usually named after a characteristic geographic site of that age.
Sometimes boundaries between epochs are marked by changes in characteristic fauna. Modern methods of imaging permit morphologists to examine details of the underlying anatomy,here the elevated ribs,which advertise a threatening retaliatory strike by this highly-venomous cobra.

Kareong America the late part of the Pliocene epoch is recognized by the presence of particular species of fossil deer, voles, and gophers. The early part of the succeeding Pleistoceneis recognized by the appearance of mammoths. The boundary or transitional time between both of these epochs is defined by a fauna that includes extinct species of jackrabbits and muskrats, but not mammoths.

Most names of epochs are not in general use and will not be referred to in this book. A specific question about designis formulated firstin any analysis. Thisis not so trivial or simple as it may sound.
A well-formed question focuses thought, suggests the appropriate experiment or line of research to pursue, and promises a productive answer. Like sound in air, lightin ether was thought to propagate by settingitin motion.
For a time, they and other scientists were stumped. As it turned out, they had asked the wrong question. Ether, as an invisible occupant of space, does not exist. No ether, no wind. They should have asked firstif ether existed! Our opinion of these physicists should not be harsh, however, because even mistakesinspire better questions and an eventual more sound answer.
In morphology, several practical tools can be used to help define the question. Supporting dissectionis the newer technique of high-resolution digital tomography, a derivative of the CAT computer-aided tomography scan used in human and animal medicine.
It is based on X-ray images made sequentially along an animal, then assembled into a 3-D overall image of the subject figure 1. It can resolve details as small as a few tens of micronsin size, even when imaging objects made of high-density materials. Another tool is taxonomy, the proposed relationships of the animal and its parts to other species.
From these techniques, we gaininsightinto the morphological design and can place this designin a comparative relationship with other organisms. The specific questions we then formulate about the structure of the organism might be about its function or evolution. To determine how a structure performs within an organism, various techniques are used to inspect vertfbrados functioning organism or its parts directly. Radiography, X-ray analysis, allows directinspection of hard parts or marked parts during performance figure 1.
Expense or accessibility, however, often makes radiography of a living organism impractical. High-speed videotape or cinematographic film can sometimes be used instead. The event, feeding or running, for example, is filmed with the camera set at a high rate of speed so that the event unfolds in slow motion when played back at normal projection speed.
The tape or film preserves a record karcong the event, and slow-motion playback permits careful inspection of motions at a speed where sudden displacements are obvious.
Natural markers—forinstance, bulging muscles or visible hard parts such as teeth or hooves—allow inferences about vertebbrados functioning of attached or underlying bones and muscles. Inferences can also be made from gentle manipulation of partsin a relaxed or anesthetized animal.

From this careful record of displacements, velocity and acceleration of parts can be calculated to describe the motion of parts quantitatively. Together withinformation on simultaneous muscle activity, this produces a description of the part and an explanation of how its bone and muscle components achieve a characteristic level of performance. Similar approaches to kidney and gland function have been used.
